Math: Ease In, ease Out a displacement using Hermite curve with time constraint

问题 I'm trying to write a method that interpolates from 0 to x (position of an object in one dimension) over time using acceleration at the beginning and deceleration at the end (ease out / ease in) with the only constraints that the total time is provided , as well as the duration of the acceleration and deceleration . the motion should replicate the inertia effect and I'm considering a Hermite curve for the non-linear portions. double Interpolate( double timeToAccel, double timeCruising, double

Drawing smooth lines with canvas

问题 So far none of the threads here on smooth lines are correct. how to draw smooth curve through N points using javascript HTML5 canvas? Smooth user drawn lines in canvas Both result in jagged lines. By smooth I mean using the x,y points as control points to make the line smooth. The line does NOT need to go through the points. It simply has to draw a smooth line given n points. Basically I'm recording each line segment, then when the user mouses up, it wil smooth the line. I've tried my own

Smoothing a hand-drawn curve

问题 I\'ve got a program that allows users to draw curves. But these curves don\'t look nice - they look wobbly and hand-drawn. So I want an algorithm that will automatically smooth them. I know there are inherent ambiguities in the smoothing process, so it won\'t be perfect every time, but such algorithms do seem to exist in several drawing packages and they work quite well. Are there any code samples for something like this? C# would be perfect, but I can translate from other languages. 回答1: You

Smooth GPS data

问题 I\'m working with GPS data, getting values every second and displaying current position on a map. The problem is that sometimes (specially when accuracy is low) the values vary a lot, making the current position to \"jump\" between distant points in the map. I was wondering about some easy enough method to avoid this. As a first idea, I thought about discarding values with accuracy beyond certain threshold, but I guess there are some other better ways to do. What\'s the usual way programs
